I have been having pain in most of my joints and stiffness. If I sit for more than 10 minutes I have a very hard time getting up. I have some thyroid nodes not ca. But my thyroid tests are normal. The pain is about a 8 on a 1-10 scale. I'm very cold sensitive. Lately my hands fingers go bluish. I also keep getting sores that take a lo g time to heal.I bruse very easily. I have very bad leg arm and around the chest cramps. That feel like a Charlie horse. And they stay very sore for days. I have been to my pcp and specialist. But no one seems to be able to know what is going on.
